This film is very intense and disturbing. The main theme is incest and there are lots of sex scenes.

A man and a woman are seen having sex several times. Her daughter is watching them. Lots of groans.

The father closes his daughter in a custody of cello and forces her to look at him and her mother having sex. A very explicit disturbing scene.

There are other sex scenes.

A young girl who's bound to a wheelchair violently stabs her own legs with a kitchen knife.

Child abuse is a central theme and is shown both physically and mentally.

A mother violently shoves her daughter down the stairs.

A man is seen chained up with all of his limbs cut off by a chainsaw.

As is always the case with Sono it comes across moderate in English but if you understand Japanese you can hear how severe it is

The English subtitled version I viewed contained mild use of profanity. There were at least a few uses of "fuck".

The music makes the non tense scenes more tense whereas silence does the same in tense scenes

There are only a handful of intense action scenes, however the overall atmosphere is very depressing. The film centers around child abuse and contains lots of nudity and sex.
